Recently I upgraded from Flyme 6.3 to 7.1 after purchasing and using for a bit, at first I thought the battery was great because the whole time I have been using it didnt drop i percent i used it for about 30 minutes. But after updating the battery was draining too fast and I timed it, it was about 30/s for every percent there was no obvious pattern sometime it would last longer but it was always under a minute. Also I reset the phone and then charged it to 85% but then when i turned the phone on it dropped to 64% so then I decided to downgrade then and there. But I wanted the features from flyme 7 is there anyway to prevent this issue and is it happening to other Meizu devices. I am a bit dissapointed that this problem is occuring as if it had happend to someone that has no knowledge on phones or has very little knowledge they would of returned the phone. Meizu's phones have great build and nice displays and software for the price but this update ruins it all please fix Meizu
